[Predisposition to type II diabetes in Ukraine residents exposed to famine 1932-1933 during prenatal development].

It has been shown in a number of studies that the early-life exposition to famine can have long-term consequences for human health. In the present study, the analysis of type 2 diabetes (T2D) prevalence in Ukraine residents born before, during, and after the famine 1932-1933 was performed. It has been found that T2D prevalence is increased in the people exposed to the peak of the famine during prenatal development compared with those not exposed to famine. Such differences are predominantly expressed in those persons born during the first half-year, and they are absent in those born during the second half-year thus pointing to the role of seasonal factors in driving famine-induced disease pathogenesis. We hypothesized that prenatal exposure to famine can result in induction of the long-term metabolic changes that have adaptive significance during early postnatal development but predispose to metabolic disorders at the late stages of life.
